Most sexually transmitted diesases go back thousands of years. Gonorrhea, for example, was first described by a Greek physician in A.D. 150, and pubic lice have been evolving right along with us since before we became Homo sapiens. This might have been one reason why it was such a shock when a strange new virus came to our attention in the early 1980s. We soon discovered that it was transmitted sexually and through infected blood, but where did it come from?

We have intriguing evidence that HIV as we know it has been in existence since at least the 1930s.

HIV has been around since before the 1980s, though it remained unnoticed and unidentified by medical science. The earliest confirmed case of HIV was in 1959, the proof found in a sample of blood from the Belgian Congo, saved in a freezer for decades and later analyzed for the virus. Other early cases of HIV infection that have retrospectively been confirmed include that of a Norwegian sailor, who must have been infected while visiting African ports in the early 1960s. He, his wife, and his child (who was apparently congenitally infected) all died in 1976, and their tissues were tested 12 years later and found positive for HIV.

Jacques Pepin — a professor and microbiologist, not to be confused with the chef of the same name — does some serious detective work to find the most plausible explanation for HIV’s origins. While he doesn’t skimp on the science, the story of AIDS’ origins can’t be told without getting into the history of Europe’s colonization of Africa in the 20th century. This period, followed by the era of post-colonization, found many societies in upheaval. Urbanization, unemployment, and migration facilitated the spread of HIV in Africa during much of the 1900s, and once it left the continent it was able to hitch a ride from host to host, traveling the world.
